Prime Dental Etching Liquid is a 37% phosphoric acid solution designed for conditioning enamel and dentin prior to adhesive procedures. With a stable, liquid consistency, it applies smoothly and remains usable without thickening over time. It’s suitable for a wide range of restorative and preventive applications, including direct composite restorations, pit and fissure sealants, and indirect restorations involving composite or metal-free ceramics. It can also be used for orthodontic bonding when paired with the appropriate adhesive cement.
To use, apply with a fine brush to the prepared surface and allow it to sit for 15 seconds. Rinse thoroughly with water and dry using oil-free air, being careful not to over-dry the surface. If a uniform etched appearance isn’t achieved, reapply for up to 10 additional seconds.
